And Without anything else to say, enjoy!

Chapter 1: Prologue

It was a normal day, the birds chirping, the clean sky, the sound of screaming and the animals in their natural surroundings…

Wait, screaming?

Yes, screaming.

The screaming was coming from a 6ft. tall 20-year-old guy who was falling from the sky while having tears in the corner of his eyes as he looks down at the fast approaching ground.

He was tanned skin, had jet black hair with brown eyes. He was wearing a black shirt underneath a dark grey zip-up hoodie, a pair of light blue pants, black sneakers with white stripes one the sides and to end it, he was wearing a black ring on his left ring finger.

"OH MY GOD OH MY GOD! HOW DID I GET IN THIS SITUATION?!" he yelled to no one as he was falling.

Before he suddenly stops screaming as he puts his fingers on his chin as if his thinking, before snapping his fingers as he remembered how it happened.

"Oh yeah, I 'died' in my world before someone calling themselves 'one above all', took my soul, made me a deal about gaining powers or something while having all of my memories and a better body" he said as he nodded his head as if agreeing of what he's saying.

Not even a moment later, he realized he was still falling before he starts to scream again,"HOW DID I FORGET I WAS STILL FALLING?!" He yelled at himself.

As he was falling, he noticed 2 things: 1) He was above a forest of some kind and 2) he noticed a town to his right as he was falling. From what he could see from where he was falling from, the town didn't seem like any town he have seen before, but before he could think any further, he hit the ground face down that made a small crater around his body.

He laid there for a few minutes without moving, before he pulled himself up crossed legged as he scratched his head, "Ow, that will probably hurt tomorrow" he said before he looks around him, only seeing the forest he saw while falling down.

"Where the hell did they send me to?" he asked himself as he stands up, having a better view now.

Before he could think more about it, he heard something move behind him, he stopped moving and talking before he slowly turned his head around, only to see something that looks like a gorilla, but colored green and purple with eyes all white with no pupils, giving our protagonist chills up his spines.

He slowly turned around to face it before standing still again, he looks into the creatures soulless eyes as he recognized what it was.

"A forest Vulcan… then that means…" He whispered to himself as he thought they didn't exist.

From what he remember back in his world a few years ago, they where usually bigger, but this one was only I little bit taller than him by a foot.

As he keeps looking at it, and knowing he can't take it on, he slowly backs away from it, trying to get away from it without having to fight it.

But before he could make a break for it, the Vulcan in front of him suddenly roars at him and starts to charge towards him, and him not wanting to die just yet, turned around and made a break for it.

As he ran for his dear life, away from the angry Vulcan and not tripping over anything, he tries to remember the way he saw the town from before while he was falling from the air, "Maybe if I get to town, the Vulcan would stop chasing me?!" He said as he kept running before turning his head to look behind him, only to see the Vulcan right behind him with its hand as it tries to grab him, only reacting on instinct, he jumped to the side as the giant hand came down to where he was just a moment ago.

"That was way too close!" he said as he keeps running after the close call.

While running, he tried to come up with a plan to either knock it out or get away from it, before he sees a tree with a branch low enough for him to grab, and him watching too many cartoon and movies when he was back in his own world.

"Please god, let this work" He said a quick prayer before he ran as fast as he could towards the branch, before grabbing the branch and pulling it back as much as he can, and waited for the Vulcan to come closer, hoping this would at least make it confused for a little bit to let him have an advantage.

He didn't have to wait for long, as he could hear its footstep and heavy breathing, and as soon as he saw just a little bit of it, he let go of the branch and let it fly back towards the Vulcan's face, making a loud sound as the Vulcan flew back and hit a tree with its back.

He fell down onto to his back as he let go of the branch and saw the ape like creature fly away from him and into a tree, knocked out as it slid down the tree with it's tongue out and a mark on it's face from where the branch hit it.

He stood up and looked with surprise present on his face, not thinking it would work, "It worked?!" He yelled before laughing, "Can't believe that actually worked!" he yelled again before he turned around and started to walk away this time.

"I've read too many manga and fanfiction to know what will happen if I stayed too long" He said to no one as he walked, "And I gotta stop talking to myself, what am I? A crazy person?" he said as he stopped walking before slapping his face, "I just answered that myself, didn't I?" he said before he sighs and keeps walking.

As he walks, he noticed he also got some new clothing, remembering he didn't own anything like these, then had a flashback from before he was falling from the sky, "Oh yeah, that happened…" he said before realizing something…

How is he still alive from falling face first from at least 10 kilometers from the sky and having a scratch on him?

He's only answer were a shrug, "Maybe I became immortal when they sent me here?" he said before chuckling as he keeps walking, before stopping and starts to think about it.

He survived from a fall from the sky, he could (almost) run faster than a young Vulcan, got faster reflexes, he knocked out a Vulcan with only a branch. After thinking all of this, his eyes slowly grow big before he looks at his hands, "What have they done to me?" He asked as if someone could hear him.

"Well Well, what do we have here? A lone mortal?" A female voice said, feeling surprised yet again as he turned his head to see something that resembled a human female, about two feet taller than him, with her horn about a foot high, got black silk like hair, black eyes with red irises, brown skin with red markings in the form of fire going up her arms, legs and face. She was wearing a black dress with a low v neck that shows off her cleavage, had no shoes and had embers going off her claw like hands.

As he just stared at her, she asked him a question, but having just ran away from an angry Vulcan and the realizations that he wasn't normal anymore.

He shakes his head and took a deep breath before he looks up at her, "sorry, was lost in my thoughts again, could you repeat what you just asked again?" he asked as he smiled up at her.

She just looks at him with a raised eyebrow before rolling her eyes at him, "I said: What are you doing in my territory, mortal?" she repeats her question as she puts a hand on her hip as she waited for him to answer her.

"oh, well where should I start?" he said before taking a deep breath and started to explain what happened before he got to where he was now, from when he died in his own world, to where he ran from a Vulcan and the thought that he might not be normal or human anymore.

She just stared at him with a blank face before she cover her mouth with her hand as she starts to chuckle, before she starts to full on laughing, "You think I'm gonna believe something like that?!" She said as she keeps laughing, him not what to make of the situation suddenly starts to laugh himself.

"Yeah, I think I know what you mean!" he said as he laughs with her.

It was only after a few minutes that they stopped laughing and took a deep breath before composing themselves.

"No really, that was actually what happened" he said with a serious expression on his face as he looked into her eyes.

Her being surprised from the sudden change from laughing to serious, she only sighs before looking back at him, "Do you really think I would just believe you just like that?" She asked as she stared at him.

"Then have you ever seen my clothes on earth-land before?" He asked as he puts his hands out to his sides as he to give her a better view of his attire.

She looks at him up and down as she starts to think about it, 'Well, now that I think about it, I did see something hit the ground and making a smoke screen from where it landed and him suddenly appearing with strange clothes on…' she thought before she looks into his eyes again, seeing that his eyes doesn't have lies in them.

Before she could say anything else, she suddenly fell down to her knees and down to onto her hands as she starts breathing heavily, before she grabs her stomach and cursed under her breath, "Damn it…" she whispered as she keeps breathing before hearing footsteps coming towards her and stops beside her.

"Hey, are you alright?" He asked as he crouched down beside her and puts a hand on her shoulder to comfort her.

"I don't have much time left..." She gasped out as she sits up on her legs, with him having his arms behind her to make sure she wouldn't fall back and get hurt more as he looks at her with concern present on his face.

"What do you mean?" he asked her as he looks at her confused, wondering what was wrong with her and, even though they just met, was worried for her.

"I'm dying… because my life span is almost over…" She said as she looks at him with a pained expression, "I'm a demon, one of the most dangerous race there is, beside dragons" she said as she made a small smile on her face, "Scared now, mortal?" she asked as she was expecting a scared expression on his face, only to get shocked to see him smiling down at her.

"Not really, I don't really care that much about what people are, besides…" He said before chuckling a little, "If you really would have me dead, I would already be down on the ground burning, right?" he said as he puts a hand on her forehead to feel if she was sick, only to pull his hand back from the way too hot skin.

She looks at him with a surprised face before a small chuckle came out of her, he looks back at her with a confused look as he wondered why she was laughing, before he could ask what was funny, she interrupted him.

"You are a strange and crazy one mortal" she said before she stops laughing and looks into his eyes, "My name is Kohaku, the fire demon queen, and could I ask you for a favor?" she asked as she hoped he would be able to help.

He smile down at her again, "Names Aiden Hugdan, nice to meet you Kohaku, and I would be happy to help in any way I can" he said, still having the smile plastered on his face as he was glad he could help.

Kohaku smiled back at him before before asking a question that would change both of their lives forever.

"What would you say of becoming a fire queen demonslayer?" She asked as she looks up at Aiden with hopes present in her eyes as she waited for his respond.

He looked at her with wide eyes as he heard what she requested, "Wait, fire queen demonslayer? How can I become a slayer if I have never used magic before? And wouldn't it take too long to learn it? You just said you don't have long again before you die and I think it would probably take years before I can…" he started to ramble as Kohaku just stared at him, not knowing what to say as she was surprised that he knew that much.

After a couple of minutes of Aiden rambling and Kohaku just waiting and staring at him, she had enough before she hits him on the head to make him shut up.

It worked since he faceplanted into the ground making a small carter around his head.

"If you would just shut up, I can explain it to you, you moron" she hissed as she stared at him sit up with his legs crossed and having a few scratches on his face while also having a nose bleed.

"Sorry about that, but please explain" Aiden asked as he was now focused on her now.

Kohaku just shakes her head at how strange this guy was before taking a breath to start explaining what she meant.

"I know a spell that will merge our souls together, meaning if we do it, my body will merge into yours and you will have all of my powers, that include: Enhanced strength and sense, more stamina, night vision, resistant to fire, fire control, eating fire, become like fire meaning that you would basically let anything go through you, and if you already are a mage, it will enhance all your other spells." She said before taking a breath and starts speaking again, "You will also get my markings and my eyes, but the down side of the spell is you will also get immortality and having me inside your head at all time." She finished as she looks at him, hoping you will still agree after all of that information she just let out.

Aiden sat still as he looks down at the ground as he let it all set in his mind before he looks back up at her, "the only downside I see is the immortality, I don't mind having you in my mind" He said as he smiled at her.

Kohaku just looks at him with a surprised face before smiling at him, "You always know what to say, don't you, Aiden?" she said as she slowly stands up, Aiden doing the same to make sure she wouldn't fall down again.

"Hey, you said my name this time, am I finally growing on you, Kohaku?" Aiden said with a teasing grin on his face as he laughs, only to stop by a fist into his stomach.

He doubled over and laid still while Kohaku still had a fist out with vein popping out on her forehead, "Don't try me, or I will hurt you more before I do the spell" she said, only to get a trembling thumps up and a whisper of "got it…".

It was only a couple a minutes later he was fine enough to stand up and ready to merge with her.

"You know, that punch would have killed a normal human, I'm impressed your still alive" Kohaku said as she pats Aiden on is shoulder.

"I don't know how I should feel that you would hit me so hard it would have killed me if I was still human" Aiden said as he sweat dropped at her comment.

"You aren't dead yet so it's fine." She said as she rolled her eyes at him before taking a few steps away from him before she stopped and turned around to face him with a serious face.

"Just stand still and it would soon be over, got it?" Kohaku asked him where he responded with a thumps up towards her.

Both Aiden and Kohaku took a deep breath before Kohaku started to cast it. After she said the first verse, she started to glow up as something that looks like embers started to come off of her and towards Aiden, who was still standing still as he saw mesmerized by the of magic, he have seen people from his world do something that they said was magic, but this was real magic.

He was so lost he didn't notice the embers coming towards him and started making the markings in his body, the same ´shape and place like Kohaku.

After what felt like and hour, the spell was done and Kohaku's body was gone, he blinks his eyes and looks around before he sighs.

"Well, that was quite a show, never thought demon magic could be that pretty" he said before he starts to walk again, looking at his new markings on his arms, before putting his hands on the top of his head to feel if he also got horns.

"Don't worry, there are no horns on there, the only visible things you got from me are the markings and my eyes, like I said before, but if you want, I can change your eyes to look like humans again" Kohaku said inside his head, and him already knowing they could talk to each other in his mind, so he wasn't that surprised he could suddenly hear a voice inside his head.

"I know, just wanted to make sure, by the way how come it didn't hurt like I thought it would?" He asked as he thought about it, whenever he either read it or saw it, whenever someone got new powers, it would hurt, like a lot.

Aiden could somehow feel her shrug her shoulders before answering, "Maybe its because you have felt some far worse than this? Like the 'accident' before you 'died', and the fall from the sky" He stopped moving as he understood what she just said, "Wait, you can also see my memories?" He asked her as he hoped she didn't see everything in his mind.

"Don't worry, only the ones that tells who you are and where you came from and all that stuff, just so I can know you better, we are on soul now, you know." Kohaku said as she assured him, "and it seems you know a whole lot of this world, and even some other too from how much you watch and read, I haven't really found that many with you together with other people, but there is something I noticed…" She said as she stopped talking.

"Yes? What is it?" He asked after he started to move again.

"It's just that, in all the memories I have gone through, there are almost to none of where you have any negative emotion, the only time was when-" Kohaku started before Aiden interrupted her, "When my grandfather passed away, I know, it's my memories you are looking at" Aiden said with a small chuckle before he sighs, "He passed away when I was 19, died of a tumor in his brain that the doctor couldn't see, sadly, I was in another country taking care of my little brother, who actually didn't know, my parents and big brother left to be there for his last day" He said with as sad tone before shaking his head, "Anyway, was where anything else you were curious about?" he asked her.

She was silent as she heard the story, not knowing what happened exactly, only the emotions.

"I was wondering: Why were you so generous, kind and honest? Whenever someone is asking you for help, you are always there to help them, no matter what, if someone asks money, you would give them and told them they don't need to give them back, and if someone need a shoulder to cry on, you are there for them, and you are always smiling, even if someone are trying to make you feel bad, so tell, why are you like this? Was there never a time where you thought you wanted something from them?" Kohaku asked, she was so confused by this person she have merged herself with, she has never met someone like him before, it was so confusing.

The only answer she got was of Aiden laughing, before taking a deep breath, "well, that's easy to answer: Because when I'm gone, I want those people that I have been generous, kind, and/or honest with, to smile whenever they ask 'remember Aiden?'. I want people to remember me, not with sadness, but with joy, I want to make people happy even after I'm dead" he said before he stops walking after a few minutes of silence from Kohaku.

"Hey Kohaku, you alright?" he asked her before hearing her sighs followed by a chuckle, "You really are a strange one, Aiden" She said, also making Aiden laugh with her.

"Thanks, I try my best" He said after he was done laughing. He could feel her rolling her eyes at him, "Anyway, any idea where we are headed?" She asked as he wondered what Aiden had in mind.

"That depends, what year are we in right now?" He asked her as he saw the town a at the edge og the forest in front of him.

"The current year is X386, why asking?" She asked him before he walked out of the forest and towards the town.

"That means in about 300 years, a certain guild will be founded and I will become a member of it" Aiden said with a smirk on his face as he could see and hear people from his position, have already seen him coming, Kohaku only said one thing.

"You are one crazy guy, Aiden, but I wouldn't have it other way"
